To all whom it mag concern:

Be it known that I,.HERMAN STRATER, Jr.., of the city of Boston, State of Massachusetts, have invented an Improvement in Combined Gutters and Moldings, of which the following is a specification:

My invention relates to the construction of those metallic gittters cross-sections'ot which shall severally sliow curves in more than one direction or one or more angular turns, its object being to so form them-of corrugated sheet metal that the corrugations shall be transverse to them.

Inthe drawings a perspective view of a 3 1 short gutter embodying. myinvention is shown in Figure 1, and a cross-section of same in The general forms of gutters are various,

andthcyare ditferently supported. The one here shown is strengthened by the horizontal bar B and braced by the transverse stay 0.

The ends are shown closed by the plain nietallic sheets D D. The sheet metal forming the body A ofthecutter is corrugated, as

5 shown and hereinbefore stated, making what may be styled a transversely-corrugated gut-,

ter. i i i t It will benoticed. that, the same sheet of corrugated metal takes more than one curve to'give shape to the body A, and that these curves are in different directionsthat is,

there are both. concave and convex curves, also, that there are angular turns, as about the bar B. Other forms may present more curves and angular turns for the same sheet of metal, and such forms will particularly ocour in moldings used simply as such.

The invention involved in my gutters and moldings will be readily understood, and I proceed to state some of the many advantages which occur in their manufacture and use,

and special applications, showing the great I can use much thinutility of my invention.

ner, and, consequently, less costly, metal and retain the same self-supporting strength.

In all gutters and moldingsbf any great length the expansion and contraction become[ a serious matter. and special joints have heretot'ore been made to allow for this motion. These joints require great care to make and keep in order. my invention by yielding to "this expansion and contraction obviates the need of said joints.

The corrugated gutters and moldings are less liable to he accidentally indented, and

dents they may receive are less liable to spread over a great extent. Moreover, the surface being regularly broken by the corrugation, which, initself, gives a better appearance, ac-

cidental irregularities do not become conspicuous as they do on planesurfaces,

Frequently gutters -and'moldings must be carried along horizontal curves, as about/the curvature of swell'front buildings; and it is readily seen that those corrugated are especiallyadapted for this purpose, being easily bent, as required, without inakingextrajoints or'forming by a (lifficult and expensive process, as has been done with those heretofore I used.
